Technical field
This utility model relates to medical instruments field, particularly a kind of laser power therapeutic instrument of the band oxygen pipe for optical dynamic therapy.
Background technology
The exposure basis of photodynamic therapy (Photodynamic Therapy, abbreviation PDT) is photodynamic effect, and this is a kind of Photosensitive reaction of the adjoint biological effect having oxygen molecule to participate in.Its process is penetrated by the illumination of specific wavelength (scope), the photosensitizer of tissue resorption is excited, and the photosensitizer of excited state is energy delivery oxygen supply, oxygen is made to generate active very strong singlet oxygen, singlet oxygen again with adjacent biomacromolecule generation oxidation reaction, produce cell toxicant, and then cause cell damage and even death.PDT generally carries out in two steps, is first to use photosensitizer to patient, is then to carry out illumination to focal zone to penetrate.
Patent No. CN201320232221.2 describes a kind of laser power therapeutic instrument, and this therapeutic instrument comprises the laser beam emitting device that can produce luminous energy, the termination that can import in tissue, and connects the optical fiber of discharger and termination.By optical fiber, luminous energy is imported to target tissue and carry out local internal radiation, the side effect that when effectively can avoid current light motor tissue external radiotherapy disease, normal surrounding tissue is impaired, reach by shortening irradiation distance the effect increasing curative effect, photodynamic therapeutic instrument has obvious curative effect to the acne that department of dermatologry is common simultaneously.But because this photodynamic therapeutic instrument can only carry out laser irradiation to target tissue, oxygen molecule required for photochemical reaction then carrys out oxygen molecule entrained in autoblood, because of institute's oxygen-containing molecules limited amount in the confession of target tissue blood, the course of reaction that oxygen molecule is generating active very strong singlet oxygen is restricted, a large amount of singlet oxygens can not be produced with adjacent biomacromolecule generation oxidation reaction, produce cell toxicant and cause cell damage and even death, and then inhibit therapeutic effect.
Utility model content
The purpose of this utility model is the above-mentioned deficiency overcoming prior art, provide a kind of can accurately at the laser power therapeutic instrument of the band oxygen pipe of interstitial irradiation's target site.
For achieving the above object, this utility model provides following technical scheme:
